I get it now.  After you use eieio to load it in, you can then have a
bit of code like this:

;; Create the database, and add it to searchable databases for Emacs Lisp mode.
(defvar-mode-local c-sharp-mode semanticdb-project-system-databases
  (list 
     ;; Code for loading in your database
   )
  "Search C Sharp core for symbols.")

You would also need to extend the semanticdb-project-database-system
class so that you can slightly update the methods used for searching,
such as semanticdb-find-translate-path.

See semanticdb-el for examples on hooking a new system database into
other types of searches.

I need to handle using statements in C++ also.  I think all you need
to do is provide an overload for semantic-ctxt-scoped-types to get it going.

Good Luck
